The administrative assistant at a software company often provides breakfast when there is a morning meeting. For last week's sales meeting, she purchased 10 dozen doughnuts and 4 dozen croissants, spending a total of $78. In preparation for yesterday's safety meeting, she spent $113 on 10 dozen doughnuts and 9 dozen croissants. Assuming she purchased the items at the same bakery both times, how much does a dozen of each cost?

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
